ROPE Lock.

Application filed July 11, 1928. Serial No. 291,790,

This invention relates to improvements in rope locks.

It is the primar object of the present invention to provi e a rope lock designed to ad'ustably secure a portion of a rope whereby a loop of an desired size ma e formed which loop wi l not slip nor tig ten and is well adapted for use about the neck of an animal, a post or other object.

A further object of the invention is to provide a rope lock adapted to be used. for hitching orswing purposes whereby a rope or the like may be 'secured or released with great rapidity.

A further object of the invention is to provide a ropelock, one of which may be secured to opposite ends of a ropel or cable permitting the quick formation of loops at opposite ends of the cable particularly adapting the 'device for use in tow lines for motor vehicles.

A- further object of the invention is to provide a rope lock of the class described which is of very simple construction, is inexpensive to manufacture,is strong and du rable, and is well adapted for the purposes described.

With the above and other objects in view the invention consists of the improved rope lock, and its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: v

Fig. 1 is a view of the end portion of a rope looped and secured by the improved rope lock;

Fig. 2 is a longitudinal sectional view of the rope lock on a larger scale, taken on line 2--2 of Fig. 3;

Iig. 3 is a plan view of the rope lock; an

Fig. 4 is a cross-sectional view thereof taken on line 4-4 of Fig. 3.

Referring now more particularly to the drawing it will appear that the numeral 6 indicates a rectangular metallic frame having rounded end portions and an elongated opening 7 .g One end portion of the frame is formed with an extension .8 of a substantial width from which projects an eyed portion 9.

Projecting upwardly from a medial portion of one side of the frame 6 is a vertical post 10 formed at its upper end portion with an integral curved supporting arm 411 projecting at right angles to the post 10 over the opening 7 and terminatngshort of the outer edge of the other side xof t e frame. The medial portion of the supporting arm 11 is curved downwardly on a radius greater than that of a rope to be used with the lock and forms a seat for a portion of a rope, as shown, the curvature being indicated at 12.

In use, one end portion of a rope 13 is passed through the eyed portion 9 of the lock and secured upon itself, as shown. Then, if the rope is to be hitched about an object it is wrapped thereabout and a medial portion of the rope, dependinof on the size loop desired, -is pinched ands passed through the 'opening 7 in the frame from below. The loop portion of the rope is next passed between the side of the frame opposite the post 10 and the end portion of the supporting arm 11, as shown in dotted lines in Fig. 4, and is then brought over and seated on the curve'd portion of the arm. When the rope is pulled the rope portions will bind against the end portions of the frame and prevent slippage and the loop will be securely maintained in its adjusted size about an object. To un-hitch the rope it is` merely necessary to raise the engaged portion of the same from the arm 11 Aand. withdraw it through the frame openin To form a tow rope, one of the improved locks may be secured to each end of the rope and then each end portion of the rope maybe quickly hitched about a portion of a vehicle and secured by the lock.

From the foregoing description it will be seen that the improved rope lock is of simple and novel construction, and is well adapted for the purposes set forth.

What I claim as my invention is:

1. A rope lock, comprising a frame having an opening therein, a post extending from a medial side portion of the frame at right angles to the plane of the same, and a rope supporting arm projecting from the outer end portion of the post at right angles thereto and spanning the frame opening.

2. A rope lock, comprising a frame hav.- ing an opening therein, a post extending from a medial side portion of the frame at right angles to the plane of the same and integral with said frame side portion, and a rope supporting arm integral with the outer end portion of the post and projecting therefrom at right angles over the frame opening and terminatin short of the opposlte side portion of the rame.

3. A ro e lock, comprising a metallic rectangular rame having an opening therein of considerably l greater length than Width, a post extending from a medial side portion of the frame at right angles tothe plane of the same and integral with said frame side portion, and a rope supporting arm integral with l the outer end portion of the post and projecting therefrom atk` right angles over the frame opening and'terminating short of the opposite side portion of the frame.

4. A rope lock, comprising an elongated .frame member' having a lock frame portion and an attaching eyed portion extending from an end thereof, the lock frame portion having an elongated opening therein greater in width than the diameter of a rope to be used therewith and of considerably greater length than width, a post extending from a medial side portion of the lock frame portion at right angles to the plane of the same, and a rope \extendin from one end thereof, of a retaining mem er consisting of a post projecting from a mcdlal slde portion of the loop portion and having an outer rope supporting arm at right .angles to the post and spanning the loop portion and terminating short of the other side portion thereof, the medial portion of said arm being curved to form a rope seat.

In testimony whereof, I ailix my signature.
